Abstract
This study updates the TEN-T investment study completed in early 2013 and
adds five new case studies to the analysis, three of which deal with mega
projects that are still in the planning or early implementation phase: Lyon-Turin,
Iron-Rhine and S21/Stuttgart-Ulm. Findings confirm that not all stakeholders
have learned past lessons on successfully developing projects. There is a
particular need for early and transparent public participation and a clear project
definition prior to the project decision. New findings suggest that measuring
wider economic benefits and European added value are necessary to justify the
socio-economic benefits of multibillion euro cross-border projects.
